airspace reviews due to the decommissioning of the Arbuckle non-
directional beacon (NDB). The geographic coordinates of the airport 
would also be updated to coincide with the FAA's aeronautical database.

ADDRESSES: Send comments on this proposal to the U.S. Department of 
Transportation, Docket Operations, West Building Ground Floor, Room 
W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590; telephone

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes the authority of the FAA Administrator. Subtitle VII, 
Aviation Programs, describes in more detail the scope of the agency's 
authority. This rulemaking is promulgated under the authority described 
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, 
the FAA is charged with prescribing regulations to assign the use of 
airspace necessary to ensure the safety of aircraft and the efficient 
use of airspace. This regulation is within the scope of that authority 
as it would amend the Class D airspace, Class E airspace area 
designated as an extension to Class D airspace, and Class E airspace 
extending upward from 700 feet above the surface at Ardmore Municipal 
Airport, Ardmore, OK, and the Class E airspace extending upward from 
700 feet above the surface at Ardmore Downtown Executive Airport, 
Ardmore, OK, to support instrument flight rule operations at these 
airports.

Comments Invited

    Interested parties are invited to participate in this proposed 
rulemaking by submitting such written data, views, or arguments, as 
they may desire. Comments that provide the factual basis supporting the 
views and suggestions presented are particularly helpful in developing 
reasoned regulatory decisions on the proposal. Comments are 
specifically invited on the overall regulatory, aeronautical, economic, 
environmental, and energy-related aspects of the proposal. 
Communications should identify both docket numbers and be submitted in 
triplicate to the address listed above. Commenters wishing the FAA to 
acknowledge receipt of their comments on this notice must submit with 
those comments a self-addressed, stamped postcard on which the 
following statement is made: ``Comments to Docket No. FAA-2021-0674/
Airspace Docket No. 21-ASW-14.'' The postcard will be date/time stamped 
and returned to the commenter.
    All communications received before the specified closing date for 
comments will be considered before taking action on the proposed rule. 
The proposal contained in this notice may be changed in light of the 
comments received. A report summarizing each substantive public contact 
with FAA personnel concerned with this rulemaking will be filed in the 
docket.

Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order 7400.11E, Airspace 
Designations and Reporting Points, dated July 21, 2020, and effective 
September 15, 2020. FAA Order 7400.11E is publicly available as listed 
in the ADDRESSES section of this document. FAA Order 7400.11E lists 
Class A, B, C, D, and E airspace areas, air traffic service routes, and 
reporting points.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 by:
    Amending the Class D airspace to within a 4.3-mile (increased from 
a 4.2-mile) radius of Ardmore Municipal Airport, Ardmore, OK; updating 
the geographic coordinates of the airport to coincide with the FAA's 
aeronautical database; and replacing the outdated term ``Airport/
Facility Directory'' with ``Chart Supplement'';
    Amending the Class E airspace area designated as an extension to 
Class D airspace at Ardmore Municipal Airport within 1.4 (increased 
from 1.3) miles each side of the Ardmore VORTAC 050[deg] (previously 
056[deg]) radial extending from the 4.3-mile (increased from 4.2-mile) 
radius of airport to 7.4 (decreased from 8.4) miles southwest of 
airport; updating the geographic coordinates of the airport to coincide 
with the FAA's aeronautical database; and replacing the outdated term 
``Airport/Facility Directory'' with ``Chart Supplement'';
    And amending the Class E airspace extending upward from 700 feet 
above the surface at Ardmore Municipal Airport by adding an extension 
within 1.5 miles each side of the Ardmore VORTAC 050[deg] radial 
extending from the 6.8-mile radius of the airport to 8.4 miles 
southwest of the airport; within 1.1 miles each side of the 315[deg] 
bearing from the airport extending from the 6.8-mile radius of the 
airport to 7 (increased from 6.9) miles northwest of the airport; 
updating the geographic coordinates of the airport to coincide with the 
FAA's aeronautical database; and removing the extension northwest of 
the Ardmore VORTAC as it is no longer required.
    These actions are the result of airspace reviews caused by the 
decommissioning of the Arbuckle NDB which provided guidance to 
instrument procedures at these airports.
    Class D and Class E airspace designations are published in 
paragraph 5000, 6004, and 6005, respectively, of FAA Order 7400.11E, 
dated July 21, 2020, and effective September 15, 2020, which is 
incorporated by reference in 14 CFR 71.1. The Class D and E airspace 
designations listed in this document will be published subsequently in 
the Order.
    FAA Order 7400.11, Airspace Designations and Reporting Points, is 
published yearly and effective on September 15.

Regulatory Notices and Analyses

    The FAA has determined that this regulation only involves an 
established body of technical regulations for which frequent and 
routine amendments are necessary to keep them operationally current, is 
non-controversial and unlikely to result in adverse or negative 
comments. It, therefore: (1) Is not a ``significant regulatory action'' 
under Executive Order 12866; (2) is not a ``significant rule'' under 
DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 
1979); and (3) does not warrant preparation of a regulatory evaluation 
as the anticipated impact is so minimal. Since this is a routine matter 
that will only affect air traffic procedures and air navigation, it is 
certified that this rule, when promulgated, would not have a 
significant economic impact on a substantial number of small entities 
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in 
accordance with FAA Order 1050.1F,

final regulatory action.
